Some time ago I wrote myself a note, "for modern sailing hulls: Leeway = 58.5
* heel angle in degrees / boat speed in knots cubed, Ocean Navigator #45 3/92
page 72. It makes sense that increasing heel would indicate increasing
leeway and that lower speeds would indicate higher leeway, but the numbers do
not seem to fit. Does anyone have the back issue to see if I wrote the
formula correctly ? My own experience is that sea state also has a big
effect.
